Fulham have prioritised Barclays Premier League survival over FA Cup progression but do not have the squad to rotate between competitions, manager Martin Jol has conceded.

Jol's side have slipped to within six points of the Premier League relegation zone having won just two league fixtures since the start of November.

They travel to face Manchester United in the fourth round of the FA Cup with Jol revealing focus on top-flight survival is paramount for the Cottagers, even if he does not have the resources to rest his key players.

"The league is the priority but we can't play different teams," he said.

"You won't see the priorities in my decision making on the teams because we still play the same team - there is not a lot of difference."

Saturday's opponents United are currently five points clear at the top of the table but it remains to be seen how seriously Sir Alex Ferguson's hunt for a first FA Cup success since 2004 is taken.

Jol believes any side, no matter their stature within the game, will target FA Cup success but admits he does not know where the competition will rank alongside United's quest for success in both the Premier League and Champions League.

"When you see the starting line-up against us on Saturday we will see what their thinking is," he said.

"I think the FA Cup is important to any club and that it is important to them as well so I can't see them doing strange things.

"Maybe they'll play a different team but, if you look at their players, their squad, you won't see the difference anyway."
